Subject: [PATCH] arm: testsuite: fix some legacy C tests

These tests all lack ISO-C style function definitions.  Some
deliberatly so.  Rather than try to adjust the code and risk changing
the nature of the test, add -std=c17 to the test options.

gcc/testsuite/ChangeLog:

	* gcc.target/arm/20031108-1.c: Add -std=c17.
	* gcc.target/arm/fp16-unprototyped-1.c: Likewise.
	* gcc.target/arm/fp16-unprototyped-2.c: Likewise.
	* gcc.target/arm/neon-thumb2-move.c: Likewise.
	* gcc.target/arm/pr67756.c: Likewise.
	* gcc.target/arm/pr81863.c: Likewise.
